FIREPLACE-HEATER FOR RADIATOR SYSTEMS.

Specification of Letters Patent.

atented Sept. 3, 190'?.

Application filed November 12,1906. Serial No. 843,011.

To all whom it may concern:

Be it known that I, WILLIAM G. CoNKLn, a citizen of the United States,and a resident of Knoxville, in the county of Jefferson and State ofOhio, have invented a new and useful Improvement in Fireplace-Heatersfor Radiator Systems, of which the following is a specification.

My invention relates to heating systems of that class in which theavailable heat from open fireplaces is utilized to heat a circulatingbody o water which, through suitable pipes, is carried through thevarious radiators of the house and is then returned again to theheater', so as to secure the advantages of an open fire and at the sametime utilize the large amount of heat which usually goes to waste inopen replaces. i

My invention consists in the novel construction and arrangement of thefireplace water heater, which I will now proceed to describe withreference to the drawings, in which Figure l is a rear elevation ofmyfireplace heater. Fig. 2 is a transverse horizontal section on line 2'-2of Fig. l. Fig. 3 is a vertical section taken on line 3 3 of Fig. l.Fig. 4 illustrates details of the packing nuts and Fig. 5 is a verticalsection through the chimney and oors of a building, showing the relationand connections of the replace heater to the radiator system.

In Fig. 5 of the drawing are shown two floors of a building with thechimney and fireplace below and two radiators R coupled up with thefireplace water heater X. The hot water supply pipe S and return .waterpipe U are both arranged in Athe chimney flue.

The hot water pipe S is tapped into the top of the water heater in thefireplace and is extended in lateral branches through the floors to theinlet sides of the radiators R and the return Water pipe U takes themore or less cooled water from the outlet sides of radiators and returnsit into the bottom of the Water heater in the fireplace. An expansiontank T is connected by pipe W with the water circulation pipe U andhasan overflow outlet Y and an inlet pipe S/ at the lower story isconnected by a suitable valve with any water supply for the purpose offilling the water heater and radiator system with water.

The water heater in the fireplace is an upright hollow iron shell X madeflat and forming the back of the lireplace and held in vertical positionby lugs K K, Fig. l, cast on the side edges of the iron back and letinto the masonry of the chimney. The hollow iron back extends from thehearth at the bottom of the replace to the offsetting shoulder ofmasonry Z forming the throat of the chimney lue and this hollow back isso set as to leave a space behind it between the water back and theinner side of the fluo, a seen in Fig. 5.

V is the grate which at the sides is anchored to the l chimney jambs andat the back is supported upon a lip or lugs .l cast upon or attached tothe water back.

D, D, D, D, are fiues extending vertically through the heater andpassing through the walls of same at the top and bottom. These lues areopen at both ends and are held in position by packing nuts E at eachend.

The packing nuts are shown i-n detail in Fig. 4, in which P, P, P, P,are holes drilled or cored in the sides of nuts to hold a spanner wrenchfor tightening or loosening the nuts. The nut is shown threaded at Q..

F, F, Fig. 3, is asbestos or other suitable fireproof packing, held inposition by the packing nut, which is intended to hold the flues inposition and also to prevent leaking around dues.

In Figs. 2 and 3, G, G, G, are ribs cast with the shell of heater on theinside to prevent buckling and to strengthen the sides of the heater.These ribs not only reinforce the flat sides against warping from thedirect contact of the fire, but they give an increased surface exposureto the water inside for more rapidly conveying the heat thereto. Theseribs are vertical and arranged between the flue tubes, or alternatingwith the same.

H2, 2, in Fig. l are holes drilled or cored in the upper and lower endsof the shell and tapped to receive the inlet and outlet pipes S and U.

G, G, are the front and rear walls of the heater and C, C, are the topand bottom walls of the heater, which are made somewhat heavier than theside walls O, C, to permit of the securing of the fines by means of thepacking nuts E, E.

A is an. extension of the back oi the shell of the heater at the top, tobe built into the chimney in such manner as to act as a baii'ler for theproducts of combustion and aid in deflecting the same into the top ofthe flues D.

N is an opening in the projection A, which is fitted with a door M,which acts as a damper to regulate the draft and heat from the firebeneath. M are lugs cast on the rear side of the door and forming partof the hinges for the same. M2 are corresponding lugs on the wall of theheater. The door is fastened by means of the rod passing through thelugs as shown in Fig. l.

M3 is alug cast on the front of door, by means of which, the damper rodM", is fastened to the door. This damper rod extends to the front of thefireplace as p iire in the grate, the damper M at the top is openedmakin ga direct draft. Then after the re is Wellstarted the damper M isclosed and the heated gases and products of combustion then 'arecompelled to dive down through the iiues D and, issuing through the openends at the bottom, rise behind and in Contact With the shell into thechimney flue where they still impart their heat to the circulationpipes. The water in the shell or Water-back thus becomes thoroughlyheated, lirst by the heat from the grate on the iront or outer surlace;secondly, from the heat imparted to the surrounding Water from the ues Dand finally from the contact of the hot gases along the back ol theshell as they rise to the chimney place.

This fireplace water heater is of simple construction and thereforecheaply and easily made. It is also adapted to the construction ofiireplaces as already built, requiring no destructive cutting oi themasonry and has such an extensive heating surface as to etliciently heata number ol radiators. Its construction and arrangement is also such asto permit it to be readily coupled up with the circulation pipes, theupright members oi which are all conveniently housed within the chimney,thus avoiding an unsightly appearance in the rooms and at the same timesecuring the largest absorption and utilization of heat rom the escapingproducts of combustion.

I claim l. A lire place water heater, consisting; oi a hollow` upright.flat, shell, havingv front and back walls and top and bottom ends, saidshell having a vertical upward ex tension o1" the back wall at the topand a vertical do\\'n ward extension of the front wall at the bottom,both said extensions being cast with the shell and formed with openings, dampers for controlling said openings, and means for operating;them, detachable flue tubes extending; entirely through the shell andthrough the upper and lower ends thereof, ireprooi packing arrangedabout the ends ol the tubes and screw nuts arranged about the ends ofthe tubes to compress the packing and form a water tight joint.

2. A tire place heater, consisting of a hollow, upright. dat, shellhaving a front and back wall with vertical ribs on the inside and topand bottom ends, said shell havingl` a vertical upward extension of theback wall at the top und a vertical downward extension of the i'rontwall at the bottoni, both said extensions being formed with openings,all of said parts being; cast in one piece. damper-s controlling saidopenings and means for operating them, und vertical iiue tubes extendingthrough the shell and through the top and bottom ends thereoi at pointsalternating with the vertical interior ribs of the shell, and alireprool' packing at the ends ol the tubes.
